My invention relates to devices for facilitating the manual transportingof sacks. Various forms of transporting sacks in a purely mechanical way are already known. These can however 5 only serve-special purposes which are locally determined, they cannot-as it is theobject of my-'invention,-assist the workmen in shouldering the sacks which lacking mechanical means of transport must be moved by labourers. It is well 10 known, that this necessity of shouldering heavy sacks needs the full strength of two cooperating men. This hard strain is done away with by my invention which consists in an apparatus of somewhat more than the height of a man and 15- which can be easily removed to any place where its work may be most efiicient.

Further details of my invention will hereinafter appear.

Fig. 1 is a front view and 2 Fig. 2 is a side View of my sack shoulderer.

Fig. 3 is a side view of another embodiment of my invention.

An iron frame 1 carries two shafts 2, one at the lower and the other at the upper end, on which chain-wheels 3 disposed on both sides from the middle line are mounted on each shaft. Preferably the lower shaft is driven by its driving wheel 4 from a motor 5 or other source of power situated on the frame 1. The chains 6 carry the lifting rods '7 and '7 which travel with the endless chains. Fixed to the frame 1 for example, by angle bars 8, 9 in an upright position is a trough 10 with its slanting lower and upper front walls 10' and 10" and in such relative position to the endless chains that the lifting rods 7 can freely pass the trough on their upward path near its open edge and on their downward path behind its closed side. Facing the open trough side is a slanting base 11. Two wheels 12 near the foot end of one frame side allow the carting of the apparatus with the help of handles 13 stuck into lugs 14 by which means the whole apparatus can be so tilted as to rest solely upon these cart wheels 12 and thus can be carted to some other place, where it is needed.

In using my apparatus the sack 15 is carted on a usual sack car upon the base 11 and unloaded so, that it covers with its bottom the gape between base 11 and slant 10' of the trough, and is leaning against its slant 10 and upright bottom, as appears in Fig. 2. During the time the labourer draws the sack car aside and has again approached the apparatus one of the lifting rods '7 has begun to lift the sack, until its upper part,v which the labourer has already gripped where it is tied, meets the upper slant v10 of the trough. On its further way upwards it is pushed by this slant gradually towards the labourer, who needs nothing but wait until the sackwithout any 5 effort of his own is thus laid on his shoulders without any push and without anybody else?s help.

In some cases where the base 11 is too cumbersome for the available space, the way of the 5 endless chain and consequently that of the lifting rods may be changed so that these rods nearly touch the ground floor, which then allows the setting of the sack directly on the ground.

It will be observed that the lower part of the R) trough is thus arranged to produce a bend in the sack so that the bottom portion of the sack is thus supported in advance of the upper portion.

By supporting the sack in this manner during its upward movement, there is no tendency for the sack to fall forward until it has reached the upper end of the trough.

In the further embodiment of my invention as shown in Fig. 3 there is no trough but instead a plurality of cross bars 16 not necessarily rigid so in themselves but held at a distance from the path of the lifting rods towards the middle line by two arms 17 for each cross bar 16 which are linked to the chain 6. As appears from Fig. 3 these cross bars travelling with the chain on their upward movement support the sack as the upright bottom of the trough did. It is possible but not necessary to provide a rigid slant Where the upper slant of the trough was, because it is easy enough for the labourer to tilt the sack after grasping it upon his shoulder. The sack is set in the same way as before. The lifting rods can be connected with the next cross bar travelling ahead of them by cloth, leather or a row of rods, wires or the like in order to provide for a better support of the lower part of the sack.

If there is no upper slant provided, the same apparatus can be used to deliver the sacks towards the back at a height equal to the upper turning point of the lifting rods. Thus the ap- 10G paratus can serve for instance to raise the sacks which are carted along the ground to some truck to be loaded to the truck level. Also the apparatus as shown in Figs. 1 and 2 can be adjusted to serve this same purpose if the upper slant instead of being rigid is linked to the trough and can be changed from the position shown into an upright one as indicated by dotted lines.

I do not confine myself to the forms of con- 1m struction as shown in the drawings and set forth in the specification.

I claim:

1. A bag support and guide for a hoisting device having a frame, an endless hoisting chain provided with spaced fiightis and arranged to move in a path which has a vertically extending portion and operating means for the chain, including pulleys around which said chain passes from rear to front at the lower end of the frame; said bag support and guide consisting of a vertical structure having a rear wall spaced rearwardly of the path of the flights in their upward movement and being arranged at its lower end to produce a bend in a bag placed against the bag support and guide and to cause the lower end of the bag to lie in the vertical portion of the path of said flights and be engaged by one of said flights as it moves around said pulleys, said bag support and guide being further arranged to tilt the upper end forwardly at the upper end of the vertical portion of said path.

2. A bag support and guide for a hoisting device having a frame, an endless hoisting chain provided with spaced flights and arranged to move in a path which has a vertically extending portion and operating means for the chain, said bag support and guide having a flat vertical central portion spaced behind the said vertical por-' tion of the path of the flights and having a downwardly and forwardly extending lower end and an upwardly and forwardly extending upper end whereby a bag placed against the lower end for hoisting will have its lower end bent forwardly and when hoisted to the upper end of the guide and support will have its upper end tilted forwardly.

3. A bag support and guide for a hoisting device having a frame, an endless hoisting chain provided with spaced flights and arranged to move in a path which has a vertically extending portion and operating means for the chain, said bag support and guide having a flat vertical central portion spaced behind the said vertical portion of the path of the flights and having a downwardly and forwardly extending lower end and an upwardly and forwardly extending upper end whereby a bag placed against the lower end for hoisting will have its lower end bent forwardly and when hoisted to theupper end of the guide and support will have its upper end tilted forwardly, said bag support and guide being further provided with outwardly and forwardly inclined side Walls.
